CROSS REFERENCE TO RELATED APPLICATIONS

This is a continuation-in-part application of U.S. patent application Ser. No. 15/041,579, filed Feb. 11, 2016 and issues on May 30, 2017 as U.S. Pat. No. 9,662,259, entitled “Anti-Accommodation Paresis Apparatus” to Nguyen, the disclosure of which is hereby incorporated herein by this reference.

BACKGROUND Technical Field

Aspects of this document relate generally to an anti-accommodation paresis apparatus, and more particularly to an apparatus that can be coupled to a computer screen to reduce accommodation paresis of a viewer.

Background

Accommodation is the ability of the eye to focus. The eye can focus very quickly under normal circumstances. For instance, the eye can view objects at different distances and accommodate or focus to allow for a vision of a sharp image. However, prolonged viewing of an object, such as a computer screen, at a fixed distance can lead to blurry vision when looking away from the object. This phenomenon is referred to as “accommodation paresis,” the transient inability of the eye to focus after staring at a fixed distance. One skilled in the art is familiar with the extensive medical research into this problem. The typical remedy of accommodation paresis is that the viewer routinely takes breaks and looks at objects at different focal points. Therapy and training is known to improve accommodation paresis.

BRIEF DESCRIPTION OF THE DRAWINGS

Implementations will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.

FIG. 2 shows another anti-accommodation paresis device.

DETAILED DESCRIPTION

The disclosure generally relates to methods and apparatus for reducing accommodation paresis of a viewer of a computer screen by moving the screen according to an automated, predetermined pattern at a predetermined speed of movement selected to reduce accommodation paresis of the viewer.

A review of pertinent medical literature shows that there is “accommodative facility training” that can increase relative accommodation, both positive and negative, to relieve paresis symptoms. The literature indicates that there is long term beneficial effect of accommodative facility training using a dioptric flip lens technique. The flip lens technique involves placing two minus lenses and two plus lenses into a holder. The user focuses through one pair of lenses at an object at near distance. When the object is clearly in focus, a flip is performed by placing the other lens into position. Repetition of this process of flipping lenses improves accommodative function.

The present disclosure relates to devices that can be used to continuously force the eye to change its focus, and constantly contract the eye muscles for accommodation while a user is performing one common activity that takes up most of many people's days—computer screen watching. As a result, the accommodation muscles are exercised to reduce accommodation paresis, eye strain, and the likelihood of blurry vision. When the computer screen constantly but slowly moves back and forth away from a viewer, the viewer's focal distance will continually change, and the viewer's eyes are not staring at a fixed distance for prolonged periods. This will cause the viewer's eyes to continually accommodate and force the accommodation muscles to continually contract. In this manner, accommodation paresis is reduced or eliminated. The distraction of a moving screen can be minimized by moving the screen at a nearly imperceptibly slow rate as not to distract the viewer. It will be clear to those of ordinary skill in the art that the principles described herein are applicable to all computer, television, and other displays that are conventionally intended for mounting in a fixed location and watched for long periods of time from a fixed location. As used herein, computer screen is intended to encompass all such displays.

An anti-accommodation paresis apparatus 100, 200 may comprise a controller 104 and a computer screen support 106 or 206. The controller 104 may be configured to emit a control signal to drive a motor 102. The motor 102 is operably coupled to the controller 104 and be responsive to the controller 104. The computer screen support 106, 206 is coupled to a computer screen 1. The computer screen 1 is, thus, mechanically coupled to the motor 102 which receives the control signal emitted from the controller 104 and operates to move the computer screen support 106 closer to and farther away from a viewer of the computer screen 1 according to an automated, predetermined pattern at a predetermined speed of movement selected to reduce accommodation paresis of the viewer.

The anti-accommodation paresis apparatus 100, 200 can be integrated into the housing of a computer monitor system 300, 400 for reducing accommodation paresis that comprises a computer screen 1 and the apparatus 100 or 200, or can be manufactured separately as merely a support for a computer monitor or screen 1. The apparatus 100, 200 can be coupled to a specific type of computer screen or universally coupled to any type of computer screens.

In some instances, a computer screen 1 may comprise a stand 2 and a platform 3 on which the screen 1 rests (FIG. 1). The computer screen support 106 can be configured to receive the platform 3. For example, in the embodiment of FIG. 1, the anti-accommodation paresis apparatus 100 can comprise a surface 5 and the platform 3, or more simply, and more directly, the stand 2 of the screen 1, can be placed on the surface 5. The platform 3 may comprise two guides 4 on opposing edges of the platform 3, or otherwise configured to engage with the computer screen support 106. For the embodiment of FIG. 1, the platform 3 is placed on the surface 5 of the computer screen support 106 with the computer screen support 106 being positioned between the guides 4 so that when the computer screen support 106 moves closer to and farther away from the user, the platform 3 and computer screen 1 move with it. Because the movement of the computer screen support 106 is not rapid or abrupt, in many embodiments the computer screen 1 and its stand 2 will be placed directly on the computer screen support 106.

The anti-accommodation paresis apparatus 100 may comprise a housing 108 that comprises the surface 5 in the form of a track 6, an inner surface 110, and a cover 11. A cover 11 can be used to protect a viewer from being injured by moving parts, and to block dust or other objects from entering into the moving parts and interfering with the operation of the apparatus.

The computer screen support 106 is configured to move a pre-set distance or distance of travel on the surface through the track 6 engaging with the drive wheel or drive gear 7. The drive wheel in the embodiment of FIG. 1 includes cogs or teeth that engage the cogs or teeth 10 in the inner surface 110. At least one free turning wheel or free wheel 9 may be located on and fitted into the track 6 for maintaining the definition or shape of the track 6 and allowing for distribution of load. The free wheels 9 can be all engaged to turn by a single drive wheel 7, which can be connected to and driven by a motor 102. A controller 104 within the motor 102 sends signals to and controls the drive gear 7 to indicate its direction and speed of rotation at particular times during its operation.

In a particular embodiment, the platform may be coupled to a stationary base through a slide or guide rails that guide the backward and forward movement of the platform. Similar to the previous embodiments, a motor and wheel may be fixed to the base of the anti-accommodation paresis apparatus on a side of or beneath the platform. The wheel may be in contact with the under-side of the platform, or the wheel may directly engage the guide-rails which are coupled to the platform. When the wheel coupled to the motor in the base turns it drives the platform back and forth along the direction as determined by slides or rails. The platform will move backward and forward in relation to the base. When the motor reverses directions, the platform will return along its path.

In the specific embodiment of FIG. 2 and other embodiments, the anti-accommodation paresis apparatus 200 may comprise a controller 104 and a computer screen support 206 that comprises an arm 12. The anti-accommodation paresis apparatus 200 can further comprise a wall mount or other fixed support 13 coupled to the computer screen support 206. The arm 12 is configured to be attached to the computer screen 1, and in some embodiments pivotally attached to the computer screen 1. The arm 12 may further comprise one or two more middle arms 15 so that the arm 12 can fold and keep the movement of the screen 1 in the direction of forward and backward relative to the viewer or the arm can swing to allow the viewer to access the screen at different locations and still allow for the forward and backward movement. In particular embodiments, the junction between the arm 12 and the one or two middle arms 15 may also be geared so that the angle of the screen 1 changes as the middle arm 15 is moved forward and backward, to enable the screen 1 to move closer to and farther away from the viewer even when the screen is angled to one side or the other.

In this particular embodiment, the arm 12 is coupled to a wheel and track assembly, which is driven and controlled by the controller 104 and the motor 102. The wheel and track assembly can comprise a drive wheel 7 and at least one free turning wheel 9. The arm 12 or the middle arms 15 can be fixedly coupled to one side of the track 6. The drive wheel 7 can have cogs or teeth that engage the cogs or teeth in the track 6 so that the drive wheel 7 drives the movement of the track 6, the arm 12, and the computer screen support 206. A cover 14 may be used to cover the wheel and track assembly for purposes of safety (to avoid nip points) and for blocking dusts or other objects from entering into the wheel and track assembly and interfering with its operation.

To limit tipping, the fixed support 13 can be clamped or affixed to a wall, an object, or a surface, or the fixed support 13 can have a weight inside to counter-balance the weight of the screen 1 and the rest of the apparatus 200 so that the fixed support 13 can be placed on a surface, such as the top of a desk.

The anti-accommodation paresis apparatus 100, 200 comprises a power source connection. The power source connection may be connected to the computer, an outlet on the wall, a stand-alone power source, or a power source within the apparatus.

In particular embodiments, the anti-accommodation paresis apparatus 100, 200 is operated by an on-off switch (not shown) to allow the user to selectively activate or deactivate the anti-accommodation paresis apparatus which continues its movement according to a predetermined pattern until it is turned off. In other embodiments, the anti-accommodation paresis apparatus 100, 200 may further comprise a first sensor 8. The first sensor 8 can be placed on the drive wheel 7 and be coupled to the controller 104. A computer use sensor may be plugged into the computer through a USB connection to detect when the computer is in use. Power is automatically sent to the anti-accommodation paresis apparatus, turning its circuits on. Additional power may be supplied to the anti-accommodation paresis apparatus through another source for powering the drive wheel and controller.

The first sensor 8 can emit an activation signal to the controller 104 when it detects that the computer screen 1 is in use. Once the activation signal is received, the controller 104 emits a control signal to the motor 102 to start or continue the process of movement. When the first sensor 8 detects the computer screen 1 is not in use, the first sensor 8 can emit a deactivation signal to the controller 104, or stop emitting the activation signal, and the controller 104 emits a control signal to the motor 102 to halt the motor 102 and the movement of the screen 1.

The apparatus 100, 200 may further comprise a second sensor which may be placed on the drive wheel 7. The second sensor is configured to sense whether the computer screen 1 has reached the end of its permitted travel or distance of travel. For example, the second sensor can sense whether the computer screen support 106, 206 has reached the end of its distance of travel either toward or away from the viewer. If the computer screen support 106, 206 has reached the end, the controller 104 can send a reverse signal to the motor 102 and reverse the travel direction of the computer screen support 106, 206, and therefore reverse the travel direction of the screen 1.

The screen 1 may be configured to move slowly enough so that the viewer is not consciously aware of the motion without particular attention being paid to the movement. The computer screen may be configured to move backward and forward, and/or in other patterns that can be used to reduce accommodation paresis. The distance of travel, the speed of movement over that distance, and/or the time to complete that distance of travel can be pre-set or customized by the viewer through a direct or wireless interface. In particular embodiments, the distance of travel of the screen 1 is set to a maximum of six inches. The predetermined speed of movement may be set to 6 inches per hour or can be within a range, such as 6 inches per hour to 12 inches per hour, with the controller adjusting the speed of movement within that range. In some instances, the predetermined speed of movement may be set to a randomized fixed or adjusted speed within the range of 6 inches per hour to 12 inches per hour. Alternatively, the settings may be configured to allow a user a choice for how much time to use to complete one cycle of forward and backward translation of the screen. This distance and speed can be changed to optimize the anti-accommodation paresis effects of the apparatus and minimize the distractive effect of the motion.

In some embodiments, the computer screen support may comprise two or more pulleys connected by straps, where tension of the straps can be increased or decreased to allow for movement of the computer screen 1. In some embodiments, the computer screen support may comprise, and be moved by, a spring that can be slowly recoiled by pressure and then expanded. In some instances, the computer screen support can comprise, be moved by, a piston that can be slowly compressed pneumatically and then released.
